Outlet duct of battery system for hybrid electric vehicle
First Claim
1. An outlet duct of a battery system for a hybrid electric vehicle, the battery system including an inlet duct for the inflow of indoor air, a blower, and an outlet duct for discharging air after cooling process, wherein the outlet duct is connected to a side member of a rear filler assembly provided with at least one inlet hole, through which air is introduced from the outlet duct, formed at a front end thereof and at least one outlet hole, through which air is discharged to an outside, formed at a rear end thereof, and the inner space of the side member is used as a flow path of air.

Abstract
The present invention provides an outlet duct for discharging air to the outside during air cooling in a battery system for a hybrid electric vehicle.
The outlet duct of a battery system for a hybrid electric vehicle in accordance with the present invention has a new structure in which the outlet duct, through which air is discharged after air-cooling of the battery system (or high voltage parts), does not extend to an extractor grill; instead, an inlet hole is formed at a front end of a rear filler assembly and an outlet hole is formed at a rear end thereof. With the structure, cooling performance can be improved. Moreover, it is possible to prevent water or dust from being introduced from the bottom of the vehicle due to the shape of the side member. Furthermore, it is possible to simplify the shape of the outlet duct, thereby improving productivity. In addition, it is possible to reduce the pressure resistance against the air flow in advance, thereby improving cooling performance.
